Welded diamond tip for durability. Provides a quick, clean way to precisely drill through the densest, most abrasive tiles, including glazed ceramic and rock hard porcelain (both solid body and glazed). Reverse spiral threads permit continuous water cooling, so you can run the bits at higher speeds without fear of overheating. Core-ejection slot removes a plug of waste material, which is ideal for repetitive hole boring jobs.

Tungsten carbide abrasive hole saw. Self-sharpening particles, so when a particle chips, a new surface is created in its place. Comes with arbor and pilot. For use with any variable speed hand drill. Cuts ceramic tile, concrete block, cement board, brick, fiberglass, plexiglas, PVC, wood with nails, cultured marble and drywall.

Diamond hole saw with 3/16" porcelain plus pilot bit, for use on all types of porcelain tile up to a scratch hardness of 8. Can also be used on granite and marble. The unique wave design allows for easier hole entrance and smoother cutting. For best results, cut holes at 400 to 600 RPMs using a liquid coolant.
